"Who's who in my zoo?"
Most tools make you
look things up.
This one already knows.
A self-hosted AI memory assistant. Your notes live in your own Cloudflare account — not ours, not anyone's. Saves people, projects, decisions, and journal entries, then answers your questions from them instantly. Like talking to your own memory.
What it is
WhosWhoZoo runs in your own Cloudflare account — not on a SaaS server. Your notes are stored as plain markdown files in your Cloudflare KV. Every chat loads your memory automatically, so the AI can answer with everything you've ever told it. Voice and text. Mobile-first.
No subscription. You pay Anthropic and OpenAI directly for usage (prepaid credits — typical use is a few cents per session). I take nothing per use. ElevenLabs voices are optional and have a free tier.
When you'd use it
Starting a new job? Remember every name, role, and quirk from your first 90 days of intros.
1:1 in ten minutes? "What did we talk about last time with Maria?" — answered before you sit down.
Family reunion coming up? Pull up your cousin's kids' names before you walk in the door.
Meeting someone twice in two years? Recall what they care about before the call.
Keeping a private journal? Save reflections, get them back when you need to remember how something felt — nobody else reads it.
What makes it different
🧠 Curated memory, not the open internet. Claude reads only what you've told it — not Wikipedia, not strangers' data, not training scrapes. Focused, confident answers about your people. No hallucinated details, no blending in facts about the wrong person.
👁️ Sees everything, every time. Every question loads your complete memory before Claude answers. No vector-search guesses, no partial results — it gets the full picture every chat, which is why it can connect across people and topics.
How your memory is organized
🖥️Active — what's loaded
People, reflections, fragments, and loops you reference often. Always in front of the AI when you chat.
📦Archive — your filing cabinet
Older records you don't need every day. Searchable on demand. Keeps your active memory lean and fast.
🔐Cold storage — rarely accessed
Long-term storage. Never loaded automatically. Recallable by name or topic when you actually need it.
Privacy & cost
🛡️ Your notes are not used to train AI. Anthropic's API terms exclude API inputs and outputs from model training by default — distinct from the consumer Claude.ai service. Your memory is processed to answer your question, then forgotten. Not stored long-term, not used to improve any model.
🔒 No account to breach. There is no WhosWhoZoo database. No central server. No "your data was exposed" email coming. Your files sit in your own Cloudflare account, reachable only with your passphrase.
🔑 API keys server-side only. Your Anthropic and OpenAI keys live in your Cloudflare Worker as encrypted secrets. They never reach the browser.
💳 No subscription — fill a bucket. Prepay Anthropic and OpenAI directly (~$5 each gets most people months). Pay only for what you use — typically a few cents per session. ElevenLabs voices are optional with a free tier.
📡 No telemetry, no analytics. This landing page has no tracker. The app has no phone-home. Nothing for me to read, ever.
📱 Built mobile-first. Voice in, voice out. Biometric unlock. Designed for one-thumb use on a phone.

How setup works
1
Get the prerequisites. Create accounts on
Cloudflare (free),
Anthropic (~$5 prepaid), and
OpenAI (~$5 prepaid). Grab your API keys from each.
2
Run the installer. Double-click the binary above. It walks you through pasting your API token + keys, then deploys the Worker and KV namespace to your Cloudflare account. ~5 minutes.
3
Open the app. The installer prints your Worker URL and a one-time Access Key. Visit the URL, paste the key, pick a passphrase, and you're in. Start adding people.
